HOT-METAL CAR.

Application. lerl June 4,

To @ZZ whomy it may concern.'

Be it known that l; JOHN D. .Foei-i, a citizen of the United States, and residing at Baltimore; Baltimore city; Maryland; have invented certain new and useful Improve ments in Hot-Metal Cars, of which the following is a specication.

The present invention relates to hot metal cars and more particularly to the type of this class of cars having a tilting or dump ing ladle.

The principal objects of the invention are to provide a car in which the spout of the ladle is constrained to follow a predetermined path in pouring; to provide means for supporting the ladle which permits movement of the ladle transversely or laterally of the car and also permits tilting movement for pouring; to provide a construction whereby the ladle is supported on the car while pouring; to provide means for limiting the travel of the spout when pouring; to provide me'ans for looking the ladle in normal or upright position; to provide a novel means for tilting the ladle; to provide means for guiding the spout ina predetermined path in combination with the novel tilting means; and generally to improve the construction of this type of cars so that the ladle thereof may be tilted with a minimum effort. Other objects and features of novelty will be apparent from the description taken in connection with the drawings; in which:

supported by a single trunnion at each end thereof;

Figure 11 is an end elevation of another modification Figures 12 and 13 are details showing different positions of some of the parts of Figure 11 when the ladle is being tilted;

Figure 14: illustrates in end elevation a further modification having a novel locking device for maintaining the ladle in normal or upright position;

Figure 15 is a side elevation of one of the locking devices; and

Figures 16 and 17 are .end elevations of the locking devices, Figure 16 showing the normal position of the same, and Figure 17 the position when the lock is rendered inoperative.

Referring to the drawings and more particularly to Figures 1 to 4L inclusive, the invention is illustrated in connection with a car having a body 20 supported on trucks in the usual manner. At each end of the body is a frame 21 the upper edge of which is formed to provide a roller track. As shown, this track consists of a central portion which is the lowest part of the track; end portions 23 which are substantially vertical, and inclined portions 24 connecting the portion 22 with the end parts 28. The ladle which has the pouring spout 26 at each of the opposite sides thereof is supported on the tracks by means of roller trunnions 27 there being a pair of these trunnions at eaeh end of the ladle. frs shown, these roller trunnions comprise a trunnion 28 rigidly secured to the end of the ladle and a ring 29 surrounding the trunnion; a roller bearing 30 being interposed between the ring and trimnion whereby the ladle is supported for lateral and tilting movements with a minimum of friction. y

It is one of the principal objects of the present invention to provide means for causing the spout to tra-vel in a predetermined path when pouring. For this purpose a saddle 31 is secured to each end of the ladle and as shown each saddle comprises a pair of laterally projecting arms 32; each arm at the end thereof having a pin 33, the axis of which is substantially parallel to the axis 5t of the ladle. Furthermore; ich pin is arl surface34 on the other.

ranged substantially in alignment longitudinally of the car with a spout. Hence if the pins 33 at either side of the car are constrained to move in a predetermined path, the adjacent spout will be causedv to travel in a like or similar path. As clearly shown vin Figures l and 3, the end surfaces 34 of the frame 21 are substantially vertical and plates 35 are arranged below the frame at each end thereof so that the outer surfaces 36 of the same are flush with and form a continuation of the surfaces 34. It will be observed that the pins 33 in the normal position of the ladle or the upright position thereof, are substantially in contact with the upper portion ofthe surfaces 34. Hence if there is a tendency for the ladle to tilt this tendency will be resisted by Vthe pins 33 at one side of the ladle engaging with their associated surfaces 34. Thus the prongs 37 between the track portions 23 and surfaces 34 in combination with the pins 33, constitute meansV for locking or maintaining the ladle yinnormal or upright position.

In the form of the invention illustrated by Figure l the ladle is adapted to be tilted by a downwardly acting' force applied to the pins 33 on either side of the ladle. For this purpose a heavy frame is utilized consisting of the parallel uprights or legs 33 connected at their upper ends by a cross bar 39. The legs l33 are guided for vertical sliding movement by means of the bearings 40 and a ring 41 adapted to be engaged by the hook of a crane is secured to the cross bar 39. The bearings 40 are disposed so that each of the legs 33 is spaced a slight disvtance from a surface34 on the frame 2l of the car and each of these legs has a laterally projecting lug 42 formed with a seat 43 adapte-d to engage the top of a pin 33. The

i weight of the frame is such that when it is allowed to descend it will push the pin 33 downward thereby tilting the ladle. It will be seen, as the pins 33 engage'in seats 43 in the lugs 42, and as these lugs have vertical movement, the pins 33 will have a corr-espondin'g movement, any departure of the pin from. this movement in a direction toward'th'e center of the car being prevented by the surfaces 34. Obviously, the seat 43 could be omitted and the pin be guided by contact with the leg 33 on one side and the ln this manner the spout will be caused to travel in a predetermined path, in this case a vertical path.

Normally the ladle is in upright position,

as illustrated iin full lines in Figure l, the axis of the ladle being` represented at 54.

It will be noted that this axis is below the pose of tilting the ladle the heavy frame is arranged at the place-where the pouring is desired. The car is run to this point and stopped when the surfaces 34 on the end frames`21 are opposite the legs 38. Then the heavy frame is allowed to descend, the

lugs 42 engaging the pair of pins 33 on one side of the ladle, thus exerting'a downward force tending to ytilt. the ladle in a clock-wise direction, as viewed in Figure l. During the first portion of the downwardmovement of the pins 33 the ladle will be simultaneously turned and pushed a little toward the left, as viewed in Figurel. This movement toward the left will continue until the'pins 33 have reached aA position substantially horizontal with 'the right hand trunnions 27 Then further downward movement of the pins 33 will cause the ladle to move laterally toward the right until the right hand roller trunnions 27 reach the position 27 indicated in dotted lines. It will be observedthat the downward movement of the pin '33 is limited by contact of the left hand trunnion 27 with the upright portion 23 of vthe roller track, this position of the trunnion being indicated at 27, Further, the lateral and tilting movements of the ladle have taken place on antifriction bearings so that the ladle is tiltedwith a minimum of effort. Again, it will be observed that during the tilting of the ladle it has been supported entirely on the car body. The path of 'the aXis of the ladle in pouring isrepresented by the dotted line a, Figure l, `the final position 54 of the axis being substantially vertically above the right. hand track.`V its the center of gravity of the ladle is generally lower, and certainly never higher thanv the axis, it will'not move outside of the track far enough so that `the moment of the weight of the ladle will be greater than the moment of the weight of the car acting at its center of gravity. Consequently, as far as the center of gravity of the ladle is concerned it does not move to any position which willcause the car to overturn. When the ladle is tilted to the dotted line position vof Figure l, the weight thereof is supported on the trunnions 27 and there is a-further' downwardly acting force due to the weight of the frame engaging the pins 33, the position of thesepins when the ladle is tilted being shown at 33. vThe resultant weight of the ladle acting on the trunnions 27 and the downward force acting on pins 33 is outside of the track and consequently there is a moment tending to tilt the car body. by the weight of the body and also by the frame,the legs 38 of which would prevent any substantial tilting body.

Although an arrangement of parts" for tilting the ladle in lclock-wise `direction Ias viewed in Figure 'l has been shown and described, it will be .ipparent thatthe ladle lllOVQlllQlll Of lill@ However this moment is resisted could he tilted in a comiterclock-Wise direction by disposing the Weighted frame at the lett ot' the ladle as viewed in FigureY l. Thus either spout 26 may be guided for pouring in afpredetermined path.

rlllhe form of the invention illustrated in Figure 3 is the saine as that shown in Figure 1 except that the ladle is adapted to be tilted by a different means which requires a modification of the structi'ire 'for causing the spout to travel in a predetermined path. The car, including the ladle and means tor supporting the saine, are the same in ths torni as in Figure 1. The ladle is provided with the usual lifting lugs 52 adapted to be engaged by a crane hook 53. For the purpose of causing the spout to travel in a predetermined path, guide-Ways lior the pins 33 are provided, these guide-Ways being 'formed between the surta/es 34 and meinbers 44 independent ol the ear each having a surface parallel to and spaced from a surface 34. As shown, these surfaces and 45 'forni a vertical guide-Way 'for the pins so that as the ladle is tilted in a clock-Wise direction the pins 33 at the right hand side of the ladle Will travel in ay substantially straight vertical path. As the spout is aligned with the said pins 33 it vrill also travel in a like path.

The movement of the ladle in tilting` is the same as described in connection with Figure 1, the extent oi tilting being limited by the lett hand trunnion engaging the prong 37, this position beingshown at 27 Fig. 3. rlhe Weight of the ladle When in tulltilted position is supported from the crane hook 53, and also on the trunnion roller indicated at 27 Fig. 3. This latter roller is not displaced laterally rom the car track tar enough to overturn the car body, the Weight of the body being more than sufficient to resist any turning moment.

In the form of the invention illustrated by Figures 5 and 6, the ladle 25 is supported on trames 121 at the ends of the car body 20 by a pair of roller trunnions 27 at each end ot the ladle. Yhe track however is of different form comprising the central low portion 122 and the tvvo curved end portions 123, although these end portions need not necessarily be curved.

JAttached to the body of the car at the sides thereof and between the spouts and the end frames 121 are the upwardly eX- tending members 137 which have vertical outer surfaces 134 Which, With the parallel surfaces 45 on the members 44, form guide- Waysl 'or the pins 33. In this. form of the invention the trunnions 27 merely support the ladle for movement transverse of the body during the iirst part of the tilting. During the greater part of the tilting movement the ladle is supported on lugs 46 carried by the prongs 137, these lugs being adapted to form pivotal seats for the pins 33. During the tilting .movement the ladle first moves slightly to the lett as viewed in Figure 5 until the pins 33 are substantially horizontal With the right hand trunnions 27, that is, until the pins engage the lugs 46. Thereafter further raising of the lifting lugs 52 tilts the entire ladle on the lugs 4G to the position illustrated in dotted lines in Figure 5. In this lorm of the car it Will be observed that the ladle is supported tor free lateral and tilting movements, the pivotal support for the ladle during the tilting being entirely on the car, and the final position oi the ladlev being higher than in Figures 1 and 3 as the vertical movement ot pins 33 is limited by the lugs 46. The prongs 137 could be located as described in connection Wit-h Figure 3, but as the pins and lugs 46 must support the entire Weight ot the ladle during the tilting, the prongs 137 are located on the frame so that the saddles 131 may be secured to the conical portions 47 or" the ladle, thus permitting a more secure fastening of the saddles t'o the ladle.

instead of forming guide-ways between the prongs 137 and members 44, they may be constructed entirely on the prongs in the manner shown by Figures 7 and 8. Thus the `prongs 237 secured to the car body, in

the same manner as shown in Figure 6, may be made With a guide slot 248, the lower end ot this slot forming a seat 246 for the pin 33 on the ladle.

In Figure 9 a modification is illustrated in which the ladle 25 is supported by means ot a single trunnion 27 at each end thereof on end frames 321 carried by the body 20 of the car. The upper edges of the` `trames 321 are each formed to constitute a track for the roller trunnions 27. As shown this track consists of the central portion 322 which is substantially semicylindrical, the substantially vertical end portions 323 and the convex inclined portions 324 connecting the end portions 323 and the central portion The spout is caused to travel in a predetermined path by the pins 33 Which travel beliu tween the members 44 and the side surfaces 334 on the end frames 321. i

In the operation of tilting the ladle, trunnions 27 irst move to the left, then return to the seat 322, then advance up the inclined curved portions 324 oit the tracks until they inally rest against the end parts 323 thereot. The ends parts 323, in connection With the side surfaces 334, thus act to limit the extent of tilting of the ladle. In returning the ladle to its upright position if the Weight thereof is not suli'icient to cause the trunnions to roll down the tracks, then the crane must be Operated to raise the entire ladle upward so that the pin 33 will travel from its low position 33 to the upper end of the guide-Way to the position shown in Figure faces 34 on the end frames.

10. Then pins 349 may be inserted in the `openings v350 formed in the end frames,`

these pins acting as supports while the ladle is lowered to its normal position. The side surfaces 334 in conjunction with thepins 33 act to maintain the ladle in its uprightposition in the same manner as described in connection withthe other forms.

Figure 11 illustrates a ladle supported on plates 21 are provided with guide vplates 451,'

two plates on each frame symmetrically arranged with respect to the vertical center line thereof. Each end;y of the ladle has a pair of oppositely extending arms 45?J each provided with a pin 453 arrangedy to engage in a guideway 454, `formed in the guide plates. These guide-ways are constructed so that as the pins 33 and spout on the associated side 'of the ladle travel downward, they will be constrained to move in a vertical path. Thus when the pins 33` have traveled to the positiony substantially horizontal with respect tothe right hand trunnions 27, the position of the right hand trunnion, pin 33, and pin 453,.vvill. be substantially as shown in Figure 12. During this part of the tilting` the trunnions 27 have moved toward the left.

" When the pins 33 reach the position shown `in Figure 13, the right hand trunnion 27 will have returned to its original position, and the pins 453 will be at the lower end of the guide-Ways 454 as shown. During the remaining part of the tilting while the right hand trunnion 27 travels from the position shown in Figure -13 to the dotted line position of Figure 11, the pins 453 will move laterally in the guide-ways 454 to the dotted line position 453 in Figure 11. Thus during the latter portion of the tilting movement, the ladle is guided by the pins 33 contacting with surfaces 36 on the plates35. The extent of the tilting movement is limited by the prongs 37 in the manner p-reviously described.. f

In Figure 14, a hot metal car 'is shown in which the ladle 25 is supported by a single trunnion 27 at the opposite ends thereof resting on end frames 521, the upper edges of these fra-mes beingformed to `constitute tracks for the roller trunnions. The ends of the ladle havethe saddles 31 carrying guidev pins 33. The prongs 537 ofthe end frames however are Vnot depended upon to lock the ladle upright, a novel form of locking device being provided for this purpose, and fthe prongs merely preventing horizontal movement of the ladle. This locking device is shown in detail in Figures 15, 16 and 17,

and the ladle is provided with two of the devices on each side thereof secured to the lower portion thereof. As shown, al latch member 55. is pivotally secured to the ladle by meansof the plates 56, the free end thereof being positioned directly against a side member of the body 2O of the car. A

ypair of links 57 are pivotally mounted` on the member intermediate the ends thereof and the free ends of these links are pivotally ysecured to a pin 58 carried by the links 59 in turnfpivotally fastened to the ladle by plates 60. The arrangement of. the links 57 and 59vis such that the member -55 normally occupies the position shown in Figure 16. In tilting thev ladle the crane hooks engage with the pins 5S thereby through the links 57 exerting a pull on the member 55 toswing it into the position illustrated in Figure 17, this movement being sufficient so that'athe free end of the member 55 can pass the side member of the car body, a bevel 61 being provided for this purpose. These devices, tl'ierefore, and the prongs 37 and 137 engaging pins 33 in the other forms constitute releasable means for normally locking the ladle so vthat it is maintained in upright position, and these means are rendered inoperilzive automatically by the tilting of the la e. f
